CDS model 5500 GC-TCD for pyrolyser systems

Most biomass contains cellulose and lignin and, when pyrolysed, generates a very complex pyrogram. The cellulose produces many highly oxygenated compounds including levoglucosan and furans, while the lignins produce primarily phenolic compounds. But both cellulose and lignin produce fixed gases including methane, carbon monoxide and water.

For several reasons, these are difficult to analyse using a standard capillary GC-MS so they are often overlooked. To better understand the levels of these fixed gases, CDS has designed an add-on feature to its trapping pyrolysers. By adding a small GC and TC detector to the outlet of the analytical trap, the user will now be capable of analysing for the fixed gases that are normally purged from the system before analysing pyrolysates from a sample.

The model 5500 is a pre-packaged GC-TCD which is a true plug-and-play option that is easily added to both new and existing CDS pyrolyser systems.
